Summary:碩士 === 國立臺北科技大學 === 製造科技研究所 === 105 === In the pass decades, gas pulsation is a major cause of pipelines vibration. In this research, the pulse velocity and pulse pressure are calculated from reciprocating compressor. Then we can know the pressure pulsation from gas pulsation after pulse pressure that is used to be as initial condition input and run. Moreover, pressure pulsations transforms shaking forces and use it as boundary conditions for pipelines vibration. We can understand the pipelines displacement and support force from the result of pipelines vibration. Before vibration analysis, we also use static analysis to confirm pipeline support and flange. Above all, the gas pulsation and pipeline vibration have been successfully analyzed with the finite element methods.
